Abstract
A high pressure pipe line air-tight drilling pressure testing device mainly resolves questions that the conventional air-tight drilling equipment cannot be utilized in a high pressure fluid infusion and gas transmission line, which is characterized in that a plunger piston (5) is arranged above the blade portion of a drilling bit (4), and the lateral wall of a cylindrical pressure vessel (3) is fixedly provided with a forcing pipe (7) with a valve (6) and a pressure gauge (8) which communicated with an inner cavity. The high pressure pipe line air-tight drilling pressure testing device can be utilized in a high pressure fluid infusion and gas transmission line, perforating and pressure testing can be one time accomplished.
Description
Technical field:
The utility model relates to the airtight boring pressure tester of drilling equipment, especially high pressure line of transfusion, gas transmission line in the pipeline construction field.
Background technology:
Transfusion, gas transmission line are in use, when the branch pipeline is installed on pipeline maintainance or the Trunk Line, need release, for utilizing airtight drilling equipment to hole usually, easy construction carries out release on pipeline, simultaneously when the pipeline pressure testing, also use this device, bore macropore behind the subdrilling aperture during boring; If when in high pressure infuser, gas transmission line, using this device, drill bit and tube wall drill through rear line inner high voltage liquid or gas can produce active force to drill bit, thereby when changing big bit drills macropore, can stop drill bit to move downward even damage rig, and then boring can't be continued, do not reach construction requirement; Therefore, this device can not use in high pressure infuser, gas transmission line.
The utility model content:
In order to overcome the deficiency that existing airtight drilling equipment can not use in high pressure infuser, gas transmission line, the utility model provides a kind of high pressure line airtight boring pressure tester, the airtight boring pressure tester of this high pressure line have can be in high pressure infuser, gas transmission line use and perforate, the one step completed characteristics of pressure testing.
The technical solution of the utility model is: the airtight boring pressure tester of this high pressure line comprises gland, packing, pressure measuring cylinder and drill bit, drill bit places in the pressure measuring cylinder, blade upper fixed at drill bit has plunger, the forcing pipe of fixed band valve and Pressure gauge and all communicate with its inner chamber on the pressure measuring cylinder sidewall.
Above-mentioned plunger upper surface is the conical surface, and its side and pressure measuring cylinder inner chamber are matched in clearance.
The utlity model has following beneficial effect: owing to take such scheme, the airtight boring pressure tester of this high pressure line is when changing big bit drills macropore, utilize high-pressure pump to pass through the forcing pipe of band valve on the pressure measuring cylinder sidewall to water filling of pressure measuring cylinder inner chamber or air, high pressure water or air enters behind the pressure measuring cylinder inner chamber can produce downward active force to drill bit by plunger, and this power can be offset the active force that liquid in the pipeline or gas make progress to drill bit; Be equipped with Pressure gauge on the pressure measuring cylinder sidewall simultaneously, can detect liquid or gas pressure in the pipeline, also can detect the withstand voltage degree of the pipeline and the parts that communicate thereof with this device; Therefore, this device can be in high pressure infuser, gas transmission line use and perforate, pressure testing once finish.
Description of drawings:
Accompanying drawing 1 is a structure cutaway view of the present utility model.
1-gland among the figure, 2-packing, 3-pressure measuring cylinder, 4-drill bit, 5-plunger, 6-valve, 7-forcing pipe, 8-Pressure gauge.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, the airtight boring pressure tester of this high pressure line comprises gland 1, packing 2, pressure measuring cylinder 3 and drill bit 4, drill bit 4 places in the pressure measuring cylinder 3, being welded with the upper surface above the blade of drill bit 4 is the plunger 5 of taper seat, the side of plunger 5 be the face of cylinder and with the inner chamber cylindrical surface matched in clearance of pressure measuring cylinder 3, drill bit 4 links to each other with rig after passing and being glanded 1 packing that compresses 2, when boring macropore, utilize high-pressure pump to pass through the forcing pipe 7 of band valve 6 on pressure measuring cylinder 3 sidewalls to pressure measuring cylinder 3 inner chamber water filling or air, high pressure water or air enters behind pressure measuring cylinder 3 inner chambers can produce downward active force by 5 pairs of drill bits of plunger 4, and this power can be offset the active force that liquid in the pipeline or gas make progress to drill bit 4; The forcing pipe 7 and the Pressure gauge 8 of welding band valve 6 on pressure measuring cylinder 3 sidewalls, forcing pipe 7 and Pressure gauge 8 all communicate with the inner chamber of pressure measuring cylinder 3, can detect liquid or gas pressure in the pipeline, also can detect the withstand voltage degree of the pipeline and the parts that communicate thereof, have can be in high pressure infuser, gas transmission line use and perforate, the one step completed characteristics of pressure testing.
Claims (2)
